Can flames be turned into a force for regeneration and growth? That’s exactly what’s happening in Queensland’s Main Range Conservation Park and National Park, where a carefully planned aerial burn is breathing new life into fire-affected ecosystems and helping futureproof them against disaster.
Last February, Queensland Parks and Wildlife Service (QPWS) Rangers conducted a large-scale aerial planned burn across parts of Main Range Conservation Park and Main Range National Park , southwest of Brisbane. The 2,600-hectare operation is part of an ongoing science-backed strategy to restore the landscape following the devastating 2019–2020 bushfires and reduce the threat of future wildfires.
‘The aim of the burn was to support the recovery of the area’s open eucalyptus communities that were severely impacted by the 2019 and 2020 bushfires,’ Senior Ranger Tim said.
While an out-of-control bushfire might be destructive, when fire is applied carefully under the right conditions it’s an essential tool in ecological restoration. Thanks to rainfall followed by clear, sunny weather, this burn took place in optimal conditions, allowing Rangers to manage the fire safely and effectively.
Using an aerial incendiary machine, the team was able to take a highly targeted and nuanced approach to apply fire across the landscape. The machine, operated from a helicopter, allowed them to strategically ignite large areas under specific conditions, utilising ignition tactics, weather, and topography to apply varying fire intensities, where needed.
‘The aerial incendiary machine isn’t just about covering ground—it’s about using precise fire application to achieve ecological outcomes during optimal burn windows,’ Senior Ranger Tim said.
‘This method supports the land’s natural resilience by creating a varied patchwork of burnt and unburnt areas.
‘Fire practitioners, contemporary and traditional, apply fire with specific intent and careful planning. While fires often start from natural causes, such as lightning, at the wrong time of year they can sometimes lead to undesirable outcomes .
‘By contrast, planned burns aim to create beneficial effects for the landscape, supporting biodiversity and strengthening the land’s resilience.’
It’s this varied landscape of different vegetation ages and conditions that supports biodiversity and strengthens the land’s natural resilience to fire—a vital technique in ecological fire management.
‘While hazard reduction is a key focus, planned burns like this one also play a big role in maintaining ecological values,’ Senior Ranger Tim said.
By keeping burns controlled and putting fire to the ground in the right weather conditions, we’re able to:
- Maintain healthy vegetation structures by managing thickening that can occur from mass germination after fire.
- Minimise the loss of important habitat features like hollow logs and mature trees.
- Create safe refuges for wildlife.
- Preserve the natural and cultural values of the landscape.
With Queensland’s hot and dry climate, managing fuel loads and supporting healthy vegetation through strategic fire application is one of the most effective ways to protect both people and the environment.
‘Planned burns like this are about more than safety—they’re about resilience.’ – Senior Ranger Tim.
Every burn is carefully planned, monitored, and adapted to the unique needs of the landscape. It's a long-term investment in the future of Queensland’s protected areas.
